Sabancaya , Perou :

The LP type of seismicity (associated with the passage of fluids), during this period decreased from an average of 13 LP / day; second, their energy is kept low.During this period there is no hybrid events (associated with the rise of magma material).The VTPS events or « proximal volcano tectonic » (very close to the volcano, less than 6 km) have increased significantly in number. Meanwhile, their magnitude experienced a moderate increase. VTPS 19 / day recorded in this period (in Report No. 01-2016, 08 VTPS / day were recorded). On January 10, 02 events were recorded with a magnitude of 3.0 ml at 10h03 p.m. and 10h07 p.m. UTC.During this period, the type of tremor events have dramatically increased in number compared to the previous period (Report No. 01-2016, an average of 07 TRE / day), with the recording of an average of 14 TRE / day; however , their energy continues to remain at very low levels.

The recording of such VT events (associated with rock fracturing) during this period, continues to be very close to the Sabancaya area, forming two seismic foci. The first home is located less than 6 km towards North-East of the crater; while the second focus (small group) is located 14 km northeast of the crater.42 VTP events (called proximals) located within 6 km radius, mainly on North-Eastern Sabancaya the crater were recorded. Among them, two earthquakes of magnitude 3.0 ml at a depth of 7 km and 10 km, about, registered on December 10, 2015 at 10h02 p.m. and 10h07 p.m. hours UTC, respectively, stand out. These events have been located at a distance of 3 to 4 km towards north – east of the craterSeismicity VTD (distal seismicity) totaled 54 events and is distributed mainly in the North – East of the crater of the volcano; an event of magnitude 4.0 ML, meaningful, recorded on January 10, 2016 at 8h43 p.m. UTC and a depth of about 6 km was declared felt by residents in Pinchollo but caused no damage.

The massive Gunung Awu stratovolcano occupies the northern end of Great Sangihe Island, the largest of the Sangihe arc. Deep valleys that form passageways for lahars dissect the flanks of the 1320-m-high volcano, which was constructed within a 4.5-km-wide caldera. Awu is one of Indonesia’s deadliest volcanoes; powerful explosive eruptions in 1711, 1812, 1856, 1892, and 1966 produced devastating pyroclastic flows and lahars that caused more than 8000 cumulative fatalities. Awu contained a summit crater lake that was 1 km wide and 172 m deep in 1922, but was largely ejected during the 1966 eruption.
